Orthopedic arthroscopic optical cannula system

Abstract

An optical cannula system can include a cannula, a body, a first tube, a second tube, and a valve assembly. An outer cannula wall can define an interior space extending along an axis of the cannula. One or more inner cannula walls within the outer cannula wall can divide the interior space into a first channel and a second channel. A proximal portion of the cannula can be received within the body. The first and second tubes can extend from the body. The valve assembly can have a first configuration in which the first tube is in fluid communication with the first channel and the second tube is in fluid communication with the second channel. The valve assembly can have a second configuration in which the first tube is in fluid communication with the second channel and the second tube is in fluid communication with the first channel.
